This is a know and unfortunately unsolved topic: See Experimental mesh leveling changes
To sum it up:
- Known to exist
- So far no systematic error in the compensation logic has been identified
- There are user reports who have successfully solved their issue. In all cases it has been mechanical issues (twisted / bent extrusion profiles) that lead to a non linear deviation between probed point and nozzle coordinates
In addition there is a first attempt to solve such issues via software: [Testers needed] X twist compensation
